Evaluating the interaction between turbocharger and engine at an early design stage could further reduce development time and cost. A Hardware-in-the-Loop (HiL) setup allows testing automotive turbochargers on a hot-gas test-bench at conditions close to the operation on the internal combustion (IC) engine. The arrangement contains pulse generators upstream of the turbine and downstream of the compressor to approximate flow conditions typical for an internal combustion engine. The setup is controlled by a real-time engine simulation model, which calculates the thermodynamic boundary conditions to be imposed on the turbocharger depending on the measured quantities. The concept was compared to measurements on a real engine from which the advantages and disadvantages of the setup are derived.
